A trove of information gathered by citizen scientists over four decades has added to the picture of how quickly climate change is affecting the Long Island Sound, which is bordered by Connecticut, New York City, and Long Island.

Citizen scientists are the volunteers, the students, the ones who consistently show up to measure, document, gather data, and learn. Their participation in a “collaborative scientific process” can help move the needle as non-scientists work with scientists to gather data, collaborate with actual analysis, and even co-create projects from design to analysis. Their contributions allow projects to scale up and keep going.

The citizen scientists of Project Oceanology, a nonprofit located in Croton, Connecticut, operate from a 22,000-square-foot educational and research facility right on the water. Project Oceanology was started in 1972 by teachers and administrators from schools in southeastern Connecticut. They focus on the marine environment in collaboration with universities and other educational institutions and have a budget of about $1.2 million.

On one of their research boats, students go out into the Thames River off Groton and learn how to measure water temperature, test the pH (acidity) and oxygen levels, and examine crabs, fish, and snails. Next year, the millionth student will step aboard one of those vessels. In all that time, over 45 years, Project Oceanology has kept the measurements of the water conditions, along with fish and invertebrate data, made by each student on every boat trip, on protocol sheets. The sheets have been stored dutifully in metal cabinets.

Hannes Baumann of the University of Connecticut and his master student, Jacob Snyder, took every recorded measurement from every one of the stored sheets. Baumann writes, “To us, it felt a bit like historians piecing together an ancient manuscript, anxious for the time when the data would finally speak. And then they did.”

A marine scientist from Project Oceanology, Molly W. Jacobs; a professor from the University of Connecticut, Hans G. Dam; and another associate professor, Michael M. Whitney; all from the Department of Marine Sciences, joined Bauman and Snyder, to author a paper, published March 21st, based on those sheets so faithfully saved over the years, “Citizen science observations reveal rapid, multi-decadal ecosystem changes in eastern Long Island Sound.”

The data drew a clear picture, showing that the temperatures in the eastern end of the Long Island Sound, which is part of the Northwest Atlantic shelf, have steadily increased, warming at a rate four times faster than the oceans, 0.45°C every ten years. Some areas of the shelf have heated up faster than 99 percent of all the Earth’s oceans. This has affected cold water species, with a decline in the American lobster, rock crab, and winter flounder.

The four decades of data also demonstrate a pH decline, creating an acidity from increases in carbon dioxide and runoff that contains things like nitrogen from fertilizers and septic tanks. The acidification of the Long Island Sound is happening more quickly than other global waters. The data also showed a slight improvement after New York and Connecticut began to address the runoff problems, around 2000.

Citizen scientists, school students, have created a strong bank of data, which agrees with other studies, such as the work of the Connecticut Department of Energy and Environmental Protection. It is difficult to predict where the strong voices to support science and the subsequent policies will come from; they might come from the middle school and high school students in a New England town.—Marian Conway

Marian Conway, the executive director of the NY Community Bank Foundation, has a Masters in Interdisciplinary Studies, Writing and a Ph.D. in Public Policy, Nonprofit Management. She has discovered that her job and education have made her a popular person with nonprofits and a prime candidate for their boards. Marian keeps things in perspective, not allowing all that to go to her head, but it is difficult to say no to a challenge, especially participating in change, in remaking a board. She is currently on eleven boards of various sizes and has learned to say no.
